Abstract: The leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia and Nicotianal rustica L., whitewash and salt water were used as materials. According to the appropriate quality ratio of materials, field control effectiveness test to cabbage worm were conducted for two consecutive years. The results showed that when the quality ratio of leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia, Nicotianal rustica L. whitewash, salt water, clear water was 4∶2∶2∶1∶1∶6, 4∶2∶0∶1∶1∶8, 4∶0∶2∶1∶1∶8 and 0∶4∶2∶1∶1∶8, the control efficiency of insecticide were 82.7%~89.8%,38.3%~42.0%,41.0%~45.4% and 52.9%~56.4%, respectively. Combine the two years experiment results, the insecticide had the best controlling effect when the quality ratio of leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia, Nicotianal rustica L., whitewash, salt water, clear water was 4∶2∶2∶1∶1∶6. The technology had obtained national invention paten.
